ABSTRACT = {Embryology of Indigofera cordifolia and I. linifolia has been studied. The anthers are tetrasporangiate. The anther wall comprises of an epidermis, middle layer and tapetum. Anther tapetum is of the glandular type and the cells are uniseriate and uninucleate. Endothecium develops fibrous thickenings when the pollen grains at 2-celled stage. Meiosis is normal and successive cytokinesis leads to the formation of tetrahedral and decussate microspore tetrads. Pollen grains are triporate and 2-celled at the time of shedding. The ovules are campylotropous, bitegmic and crassinucellate. Meiosis in megaspore mother cell leads to the formation of linear tetrad of megaspores, The chalazal megaspore of the tetrad is functional and develops into monosporic Polygonum type of embryo sac. Antipodals are three in number and are ephemeral. Endosperm development is of the Nuclear type and the embryo development conforms to the Trifolium variation of the Onagrad type of Johansen and Period I, series B2 and Megarche type VI of Soueges.},
